Flex Help! Urgent before he changes his mind!

Should I trade Alvin Kamara for Michael Thomas in a standard league? I don’t know who will be better rest of season. I’m thinking that Thomas is a better bet because Kamara is splitting touches but it seems like Kamara may eventually take over Ingram’s spot. Am I silly for thinking this helps my team, who will be better rest of season standard league?

In a flex spot id rather play a RB if I can… So unless you have tons of RBs and no good WRs. I wouldn’t do this for a flex spot.

My team is
QB: Dak

I also have Devin Funch and Juju on my bench and was thinking about adding them and also receiving Engram. Also have Olsen on my bench but am unsure what his vaule will be when he comes back.
